Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

Dodge Vipers selling for $480k in China

Want to get your hands on a new Dodge Viper? Be prepared to pay dearly. It starts at nearly $90k here in the US, but that's nothing compared to what you'd have to pay for one if you lived in, say, China. CarsNewsChina.com reports on one Viper available in Beijing for an eye-watering 298 million yuan – equivalent to about $480,000 at today's exchange rates and representing more than a 500-percent markup. Part of that premium comes down to the Chinese tax code that charges a reported 60 percent for anything with an engine displacing over four liters. And the Viper's, we needn't remind you, is more than twice that. It naturally costs some to import a car to China as well, but most of the rest is pure profit. The Beijing dealership reportedly gets the cars from dealers in California, has already sold three and plans to import several more. The dealer can also get you (or wealthy Chinese individuals) a Corvette Stingray for a comparatively cheap 1.73 million yuan (or $280k). Related Video:

Dodge Scat Pack for 5.7L Hemi V8 detailed, priced

Dodge revived the Scat Pack name back in November at the 2013 SEMA show. At the time, though, we were short of details on forthcoming upgrade packages, which were destined to add some oomph to the Challenger, Charger and Dart. We're still waiting to hear about the upgrades to the Dart's 2.4-liter four-pot, but Dodge has gone ahead and released the details on the upgrades to the 5.7-liter Hemi V8 in the Challenger and Charger R/T.
As we detailed in our original post, three different Scat Packs will be available that will allow customers to upgrade their cars without voiding the warranties. Starting with the $2,195 Stage 1 kit, owners will net an extra 18 horsepower and 18 pound-feet of torque thanks to a Mopar-branded cold-air intake, exhaust and ECU ref lash. Stage 1 is also the only package that could be installed outside of a Chrysler-authorized service center without voiding the warranty (a mechanically competent owner could even do it at home, we're told by Dodge). Stage 2 builds on the entry level Scat Pack, and adds performance camshaft kit, which boosts output over the stock 5.7 by up to 30 hp for $1,895. As with the Stage 1, the ECU is tweaked.
For those that want to go whole hog, they can add the Stage 3 for $4,995. The top-tier gets quite serious, adding CNC-ported cylinder heads, as well as high-flow headers and cats. Output over stock is 58 hp and 47 lb-ft of torque. Each kit comes with a pair of badges, just in case owners want a bit of visual flair.
